In the following list of species, the stations are arranged alpha- 
betically by townships. The records are all based on material 
collected and preserved by the writer, except where otherwise stated. 
References to Connecticut specimens in the literature are definitely 
indicated. Citations for the names of species and varieties are given 
only in those cases where the forms in question are not found in the 
four published volumes of “A Monograph of the British Desmidi- 
aceae,” by W. & G. S. West. The sequence followed is that adopted 
by these authors in their first volume. 
In the preparation of this report, I am very much indebted to the 
helpful criticism and inspiration of Dr. Alexander W. Evans, under 
whose direction I commenced and brought to a conclusion this report. 
I am likewise very much indebted to Dr. Nellie Carter, who during 
the past year was a research fellow at the laboratory. Her critical 
knowledge of the group was an invaluable aid to me in identifying 
the material; without her assistance this report would have been an 
impossibility.
